研究了纳米ZnO对斑马鱼肝脏生理生化指标的影响。当斑马鱼暴露在ZnO纳米颗粒浓度为2.8 mg/L、5.6 mg/L、11.2 mg/L、22.4 mg/L和44.8 mg/L时,分别测定了6 h、12 h、24 h、48 h和72 h时斑马鱼肝组织中的GSH、MDA、Na+K+-ATPase的含量和24 h ROS的变化,结果显示:与对照组相比,处理组中斑马鱼肝组织中GSH的含量显著减少( P<0.05),MDA含量随处理浓度的升高却显著增加( P<0.05),Na+K+-ATPase活性随暴露时间先显著降低后显著升高( P<0.05),24 h ROS含量高于对照组( P<0.05),说明斑马鱼肝组织的生理活动受到ZnO纳米颗粒的影响,且有时间和浓度依赖性。
研究瞭納米ZnO對斑馬魚肝髒生理生化指標的影響。噹斑馬魚暴露在ZnO納米顆粒濃度為2.8 mg/L、5.6 mg/L、11.2 mg/L、22.4 mg/L和44.8 mg/L時,分彆測定瞭6 h、12 h、24 h、48 h和72 h時斑馬魚肝組織中的GSH、MDA、Na+K+-ATPase的含量和24 h ROS的變化,結果顯示:與對照組相比,處理組中斑馬魚肝組織中GSH的含量顯著減少( P<0.05),MDA含量隨處理濃度的升高卻顯著增加( P<0.05),Na+K+-ATPase活性隨暴露時間先顯著降低後顯著升高( P<0.05),24 h ROS含量高于對照組( P<0.05),說明斑馬魚肝組織的生理活動受到ZnO納米顆粒的影響,且有時間和濃度依賴性。

The effects of nano ZnO on the physiological and biochemical index in the liver of zebra fish were studied in this paper .Ze-bra fish were exposed to the different concentration ( 8 mg/L, 5.6 mg/L, 11.2 mg/L, 22.4 mg/L and 44.8 mg/L) of the nano ZnO. The contents of GSH, MDA, and Na +K+-ATPase in the liver were detected at 6, 12, 24, 48, and 72 hours.Changes of 24 h ROS were also detected .The results showed that the content of GSH in the liver tissues was significantly lower than that in the control group ( p<0.05 ) , while the content of MDA in the liver tissues was significantly increased ( p<0.05 ) with the increasing concentration of nano ZnO.The activity of Na +/K+-ATP enzyme in liver tissues was significantly decreased at first , and then increased ( p<0.05 ) with a longer exposure time .The content of changes of 24 h ROS in the liver was higher than that in the control group ( p<0.05 ) .Ex-perimental results showed that physiology in the liver tissues of zebra fish was affected by the ZnO nanoparticles and also depended on the time and concentration .
